To check on whether you need to refinish or just thoroughly clean older wood furniture, first try cleaning the piece a few times using a good furniture cleaner on a cotton cloth. Let it dry between tries. If the wood finish begins to clear, proceed with cleaning. If it remains dark, marred or alligatored, then refinish.
Before placing young plants in the garden they should be hardened off. Plants taken directly from the house to the garden almost always scorch from exposure to direct sunlight and wind. Scorched plants turn white or brown. Plants not killed will certainly be set back. Harden off seedlings by placing them outdoors for several hours on mild days. Select a shady, sheltered area at first. After several days provide some sun in gradually increasing amounts. Plants may be left outside at if temperatures are mild. Begin this process at least two weeks before the plants are to be set out in the garden.
